Its thick leaves are oblong-shaped (2-6” long, 1-4” wide) with pointed tips and 5 deep main veins. The lower leaf surface, as well as the reddish stems, are covered with stiff hairs. It bears small white flowers, only about ½” wide, with 5 petals each. The fruits are oblong-shaped, small (upto ½” long), and purple to black in color. Distribution: Koster’s Curse can be found along roadsides, in pastures, and in mesic forest. It has been identified in areas including; Volcano, Mountain View, South Kona, North Kohala, and Hilo. Other Information: C. hirta is considered extremely invasive. Like many other exotic plants, it tends to grow up and over native plants, thus smothering them. It also tends to grow in very dense patches which block out light from the ground, thus preventing native seeds from sprouting. Agriculturally, C. hirta is a problem because it can easily get established in pasture lands.

It is also found on Kaua‘i, O‘ahu, and Maui. Other Information: T. urvilleana can grow in very dense stands, so thick that a person can barely walk between the branches. It grows easily from cuttings; people have been known to take cuttings from Volcano and plant them around the island. It was originally brought to Hawai‘i as an ornamental plant.

Greenish inflorescences upto 1’ long occur at the ends of long stems. Its seeds are tiny, less than 1/8 of an inch long! Distribution: Palmgrass can be found at elevations of 500-5,000 feet, most noticeably in the Waiakea and Ola‘a areas. It grows along roadsides, as well as in disturbed forest and agricultural land. Other Information: A local name for this grass is “itchy grass”. The reason for calling it by that name is because of its stiff hairs. When you touch this plant, the stiff bristles get stuck in your skin and can make you itchy! It is believed to be spread by birds.
